Available in PDF, EPUB and Kindle. Book excerpt: Transition metal complexes containing imido ligands (M=NR) are an important class of coordination compounds implicated in nitrogen-group-transfer reactions such as aziridination. The present thesis investigates the formation of iron-imido complexes via deoxygenation of iron-nitroso complexes that have a nitroso (RN=O) functionality tethered to their main ligand framework. This process is at the heart of important oxygen-atom- transfer (OAT) reactions such as the epoxidation of alkenes or the hydroxylation of organic substrates. For this purpose, the new pentadentate monoanionic ligand BPAEBNHOH was synthesized and disproportionated by Fe(II) salts to yield N-bonded monomeric iron-nitroso complexes [Fe(II)BPAEBNO(OAc)] (1) and [Fe(II)BPAEBNO(MeCN)](OTf) (2) as well as the iron-amine complex [Fe(II)BPAEBNH2(OAc)]. These complexes were characterized by X-ray crystallography and spectroscopic techniques. Complexes (1) and (2) were found to be able to perform OAT to phosphine reagents (PR3) in moderate to high yields. Although not isolated, iron-iminophosphorane (M-N=PR3) compounds were identified as the main products of the reaction. Detailed kinetic and mechanistic studies of this reaction suggest that the mechanism does not involve a simple rate law. Control experiments and comparisons with the literature suggest that the mechanism involves the replacement of acetate and acetonitrile ligands with a phosphine ligand, before the nitroso group is deoxygenated. These results suggest the formation of an iron-imido intermediate, prior to its trapping by phosphine reagents.

Book Transition Metal Dinitrogen Complexes

Download or read book Transition Metal Dinitrogen Complexes written by and published by . This book was released on 1973 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The central concern of this Thesis is the basic character of transition metal dinitrogen complexes towards Lewis acid moieties, with which they may give adducts containing the structural unit M-N-N-M' (M' is a Lewis acid moiety). This study was prompted by an interest in the problem of nitrogen fixation, since adduct formation is one of the few reactions of coordinated dinitrogen.Nitrogen fixation and certain aspects of base behaviour among transition metal complexes are reviewed in Chap. 1.The formation of adducts of dinitrogen and carbonyl complexes with AIR^ (R = Me, Ph and Cl) is described in Chap.2 and a base ranking of some of these complexes is drawn up from p.m.r. studies of equilibria involving the adducts (R = Me) and diethyl ether (Chap. 3 )* Adducts of trans -[ReCl(XY)(PMe2Ph)^] (l) (XY = N 2 ) with Mo- and W-(lv),-(V) and -(VI) acceptor moieties are described in Chap. Z*. The reactions of certain of the Re(l) dinitrogen complexes with the halogen acids HX are also discussed (Chap. 6).The bonding of N 2 and CO to transition metals is discussed (Chap. 7 )» with reference both to published physical measurements on their complexes, and to measurements of the dipole moments of the analogous complexes I (XY = N 2 and CO), described in Chap. 5.The preparation of some novel dinitrogen and carbonyl complexes is described in Chap. 8.
